On August 26, 1791, John Fitch was granted a United States patent for the steamboat. He went on to build a larger steamboat which carried passengers and freight between Philadelphia and Burlington, New Jersey. Fitch was granted his patent after a battle with James Rumsey over claims to the invention. Both men invented similiar inventions. John Fitch constructed four different steamboats between 1785 and 1796 that successfully plied rivers and lakes and demonstrated, in part, the feasibility of using steam for water locomotion.
